Bonneville electics Help wanted

[triman65]

Help can anyone tell me where to get a diagram for the bonneville T120. I have a Haynes manual but none of the 120 diagrams show the indicator wiring.
The indicator flasher stopped working and I renewed it and now it flashes the ignition warning light. I only changed the two connections and tried them both ways round and still with the same result.

Any help would be appreciated

Sounds like a short somewhere, I take it the flasher unit was a direct replacement of the correct polarity.

It's in the 1972 T120 factory manual.

As you have a Haynes (unit twin?) manual, that should also include the 750 T140/TR7 models? So the indicator wiring layout for the T140/TR7 is basically the same as it would be for a late T120.

What year is your Bonneville?

If it is a late enough model to have had indicators originally, then the "ignition warning light" shuld be an oil pressure warning light.

I only changed the two connections and tried them both ways round and still with the same result.

I can only think that something has been connected up wrong, or as Hunter has already said, there could be a short somewhere in the wiring, as I can't see how that particular warning light would flash otherwise?

Thanks L.A.B and Hunter for your advice. It is a short somewhere and have spent the last 2 days trying to find it. No luck. The wiring loom could be original as the cloth cover is rotten so will attempt to rewire it

May have to ask further questions so please do not leave the Country

Many thanks Mick

Unfortunately, Mick, you didn't answer my question about which year model it is, so I can't offer you any suggestions about where the fault may actually be, as I don't know which model year wiring it's got, and whether it's an ignition warning lamp, or oil pressure warning lamp (1969-on)?

Presumably there is also a flasher warning lamp? If so, is that working or not?
